D.R.D,

That's news to me. I went that route cause I didn't want the triggers or grip that came with most other LPK. I wanted a kit from Ares Armor but they were out of stock. They said any DPMS LPK would work. I will test fit everything before I install it permanently. Do you have another LPK in mind?

Thanks,

Well just in case I purchased the Fulton Armory LPK without trigger. So I'll wait and install it. I think Red Barn will take the CMMG kit back or I may toss it in my parts bucket to use the springs and such in an emergency.

What scope mount would you go with for the SWFA 16X scope? I was gonna go 12x but I'm not getting any younger so may as well have too much scope than not enough. Thanks to you all for your help!

What scope mount would you go with for the SWFA 16X scope?

 

Ever plan on needing to take it off?  if so, there are several good one-piece mounts out there.  One of the most affordable (and tough as hell) is the Armalite.  No kidding.  You can go up in price from there.  I have one Bobro mount, and that thing is just pure sweet.  I have a few ADM mounts, and love 'em.  It's up to you, really.

 

If you never intend to (or foresee the need to) take the scope off, then one of the best values is the Warne Maxima steel rings.  You can get those in a QD version as well.

I have never hear a bad word said about the Larue mounts, and American Defense have a good rep for less $$$$

I found out the same day my second scope arrived, that my second set of Warne rings was on back order, so I paid a couple bucks more from fleabay to get a set sooner..

I really like the Warnes....

Well after adding up my build sheet, a BOBRO or LaRue mount is kinda out of the question! I did buy the lower jig, new drill bits, and an upper vise block but still! DAMN!

The Warne QD rings I think are the ticket. I want to buy them with the SWFA scope to save some shipping costs. I am not 100% sure which rings to order. I know the scope is 30mm tube.

I hate to ask but would you be able to share a part # for the Warne QD rings? Sorry I ask, just don't wanna do the "trial and error" deal. I realize it's a fine time to get cheap! That being said any info would be great! I just laid all my build parts out and this rifle will be sweet! Thanks to all the help everyone. I will do a "Build" post with pictures when I'm finished!

You want the 217 version, ultra high.

I have these aluminum ones. They are The A217L, if you want steel they are 217L and cost about $30 more.

You get $10 off if you sign up for the mailing list.

They have extra high (216) and ultra high, you want the ultras.

  I also use extra high rings on all my AR's, but its how your cheek weld on the stock that dictates how high of a ring you will need . A lot of it is trial & error or there are ways to take some rudimentary measurements to get close to a size or height. Ring or mount manufacturers have different ways of coming up with their height spec's . 

 The last two ring sets I bought were Warne  QD , but I also like the Burris Extreme Tactical rings . All that have been mentioned above are good choices also.  Hard choice to make  .

Angel,

Thanks for the specific info. It really helps.

Can I ask a dumb question? Why Ultra High ones? I saw the Burris P.E.P.R mount on SWFA's website. Any thoughts?

Thanks again for all your help!

PasoGunner

The ultra highs just barely cleared my Matech rear BUIS.

If you don't run a BUIS, you can run a high or extra high.

I have a non QD Burris PEPR mount and it's nice enough, but feels clunky, and costs more than the Warnes.

If you don't like the Warnes I'll trade you the pepr, but then I gotta build another rifle...

I will be running magpul MBUS on this rifle for now. I never thought about needing high rings so the scope would clear them. Thanks for the heads up. I will more than likely get the Warne rings. BOBRO looks awesome but gotta save a little money! Gonna see if SWFA sells the rings when I buy the SWFA 16x mil/mil scope. This rifle is gonna be more than I ever hoped. Now I gotta do my part and mill the lower carefully

I have read people complaining larue chews up your rail. if I was spending that sort of scratch id go with bobro every time.

I've read that too, and while I've seen wear marks (mostly grease transfer from where it locks onto the rail) I've never had an issue with my LaRue mounts (LT104, LT120, LT660, LT139, LT123). I move my stuff around pretty often too...

Paso, before you buy any mount or rings, run the math.

 

You need to keep the scope as low as possible.  As close to bore centerline as you can.

 

I don't run a single set of extra high rings on any AR.

 

You don't need extra high rings to clear a rear sight - if you do, then look for a smaller profile rear sight, and set the rifle up differently.  On very few rifles, will you ever be flipping up a rear sight and running it through your scope anyway - if your scope isn't a true 1x magnification, then your iron sights will never properly focus through it anyway.  On anything 3x minimum magnification, you can't see the front sight post through the magnified optic anyway.  In almost all circumstances, if you have to resort to removing the optic, and going to back up sights, then you're removing the magnified optic to do that.  That's where QD attachment comes in handy.  On that very note, if you're removing your magnified optic to resort to your back up sights, then something bad happened anyway, and the scope is now a throw-away - most of the time, in most reasons when you'd need to remove it.

 

Measure, run the math, and get the lowest rings you can get away with.  Warne lists their method of measurement right on their website.

98Z,

Thanks for that input. I never really thought of that. Not alot of reason for back up sights anyway. I am not an operator (well I am a power plant operator) so I will not be going to war. I will do the math and go from there!

Thanks again

You never know, man.  You might be hunting with that rifle, drop that bastard out of a treestand, and eff your scope all up.  In that case, remove the scope, continue the hunt with your iron sights, which are zero'd for 300 (if they are).  No need to come home "empty," just because of a broken scope.

 

There are many reasons to have to remove it - mostly, none are good, though.

 

Don't totally ditch the option of having back ups.  just set it up right, brother.
